如何將查詢的結(jié)果保存到數(shù)據(jù)庫(kù)？

答：分兩種情況，如果表已經(jīng)存在了

insert into somedatabase.sometable select distinct username,ddname,college,somedate,id from test_table where somedate>='20180101'and sdate<'20180130';

表不存在：

create table somedatabase.sometable as select distinct username,ddname,college,somedate,id from test_table where somedate>='20180101'and sdate<'20180130';
